For quick and easy cartography, “My maps” service from Google allows to make and publish online maps.
A csv with coordinates can easily be uploaded. It also supports drawing of points, polygons and polylines on multiple layers.
Maps are easily modifiable using a smartphone: a must have for field cartography
Note that the export format is kml/kmz. The kmz exported can be unzipped with any zipping utility returning a kml. The kml can be imported directly in R using readOGR in the the rgdal package. It can also be imported in QGIS and from there exported to many formats.
This significant expertise on the access to primary care in the Philadelphia, PA involved several of our key know-how:
- Data Management with merging of practitioners and population information from over 10 data sources
- Spatial analysis based on driving distances
- Cartography with the constitution of interactive Google maps involving spatial statistics under the hood
- Web development to interface the whole
It is reaching an end with the recent delivery of the review report.
Our next steps are to:
- Make available online the interactive map engine, without proprietary data
- Publish in medical journals the key findings of the study (yes, access to care has social determinants…)
We will keep you posted.
